摘要： 异色瓢虫是一种重要的捕食性天敌，可捕食多种蚜虫，在生物防治中具有很大应用前景。研究了异色瓢虫对3种蚜虫(即菜缢管蚜、禾谷缢管蚜和白杨毛蚜)的捕食功能反应。结果表明：异色瓢虫对3种蚜虫的日捕食量中，其中四龄幼虫最大，成虫和三龄幼虫次之，1、2龄幼虫最小。捕食者对猎物的功能反应均属于Holling-Ⅱ型方程。

Abstract: Harmonia axyridis(Pallas) is one of the important predations, and it can prey many kinds of aphids, it has very useful foreground in biological control. The functional responses of Harmonia axyridis(Pallas) on three species of aphids[ Chaitophorus populeti (Panzer), Rhopalosiphum padi (Linnaeus), Lipaphis erysimi (Kalteback)] were investigated in the laboratory. The results showed that the 4th instar larvae had the biggest daily predation capacity，followed by adults and the 3rd instar larvae .The smallest is the 1st and 2nd instar larvae. The functional response of Harmonia axyridis(Pallas) to aphids was simulated with models of Holling-Ⅱ.
